UKA1A220MDD

The UKA1A220MDD is a radial-lead aluminum electrolytic capacitor with a nominal capacitance of 22 µF and a rated voltage of 10 V. It is designed for compact, through-hole assemblies and optimized for audio applications where stable filtering and decoupling are required.

Key product attributes include a wide operating temperature range (−55°C to 105°C), 2000 hours endurance at 105°C, AEC-Q200 rating, and small form factor (φ5 × 11 mm). Product status: End Of Life.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance with ±20% tolerance at 10 V rating, suitable for decoupling and local energy storage in low-voltage audio circuits.
• Ripple Current Performance — Low-frequency ripple current rating of 45 mA (120 Hz) and high-frequency ripple current rating of 90 mA (10 kHz), supporting common audio power-filtering demands.
• Low Leakage & Reliability — Specified leakage current of 6.6 µA and endurance of 2000 hours at 105°C; leakage and end-of-life behavior are defined by the series endurance testing.
• Wide Temperature Range — Operates from −55°C to 105°C, enabling use across a broad set of environmental conditions.
• Package & Mounting — Radial lead can (φ5 × 11 mm), lead spacing 2.0 mm (±0.5 mm) for compact PCB layouts; available in bulk (no terminal forming) or bag packing.
• Polarized Electrolytic Design — Polar capacitor intended for DC applications requiring polarized energy storage and smoothing.
• AEC-Q200 Rated — Meets AEC-Q200 requirements as indicated in the product specifications, supporting use in designs that reference this passive-component qualification.

Typical Applications

• High‑grade Audio Equipment — Local power-supply decoupling and smoothing where compact, low-leakage capacitors help maintain audio signal integrity.
• Audio Signal Processing Modules — Filtering and bulk storage in preamplifiers, DAC/ADC front-ends, and small amplifier stages.
• Compact Consumer Audio Electronics — Space-constrained PCB designs that require through-hole mounting and reliable operation across a wide temperature range.

Unique Advantages

• Compact form factor: φ5 × 11 mm can size and 2.0 mm lead spacing enable dense PCB layouts and easy placement in small assemblies.
• Designed for audio use: Series positioning for high‑grade audio equipment aligns the part’s electrical characteristics with common audio filtering needs.
• High-temperature endurance: 2000 hours at 105°C provides predictable lifetime behavior in elevated-temperature environments.
• Low leakage: 6.6 µA leakage current supports low-bias-loss applications and helps preserve DC operating points in audio circuits.
• Frequency-aware ripple handling: Specified ripple ratings at both 120 Hz and 10 kHz give designers explicit values for low- and high-frequency filtering performance.
• AEC-Q200 rating: Conformance to AEC-Q200 provides an added level of component-level qualification referenced by some design flows.
